I've seen several Scala heavy duty yagis in use on USGS earthquake seismograph transmitters here in Southern Calif. I liked what I saw and got a catalog from Scala. They also make corner reflectors.
And they are a USA company - in Oregon. http://www.kathrein-scala.com and click on "30-512mhz", then "Other Directional Antennas". The high band ones are on page 1, the UHF ones are on page 2. None specifically say "corner reflector" - you almost have to know what to click on. If you want a printed catalog there is a catalog request link on the page. The UHF two that you probably will be most interested in are http://www.kathrein-scala.com/getdata.phtml?id=219 http://www.kathrein-scala.com/getdata.phtml?id=227 But be aware, Scala products are built for the commercial broadcast market, are built to to survive very severe weather, and are priced accordingly. Because of this several local hams have created homebrew versions of their products. The reflector array of a UHF or high band corner reflector is not hard to create from copper plumbing pieces and brazing rod. The driven element is a simple dipole.
